Detailed description

In the tobacco compositions described herein, the tobacco component contains reconstituted tobacco obtained in a manner similar to paper. The tobacco component may also contain leaf tobacco, pressed tobacco, and/or strip cast tobacco.

With respect to the tobacco compositions described herein, the tobacco composition may contain a filler component. The filler component is in most cases a non-tobacco component, that is, a component that does not contain ingredients derived from tobacco. The filler component can be a non-tobacco fiber, such as wood fiber, or wood pulp, or wheat fiber. The filler component can also be an inorganic material such as chalk, perlite, vermiculite, diatomite, colloidal silicon dioxide, magnesium oxide, magnesium sulfate, magnesium carbonate. The filler component can also be a non-tobacco cast or pressed material

From non-tobacco material. The filler component may be present in an amount from 0 to 20 95 by weight of the tobacco composition or in an amount from 1 to 10 95 by weight of the composition. In some embodiments, the filler component is absent.

With respect to the tobacco compositions described herein, the tobacco composition contains an aerosol generating agent. In this context, an "aerosol generating agent" is a means that facilitates the generation of an aerosol. The aerosol generating agent may facilitate aerosol generation by facilitating the initial vaporization and/or condensation of gas to produce an inhalable solid and/or liquid aerosol. In some embodiments, the aerosol generating agent may enhance the delivery of aromatics from the generating material. aerosol.

In general, any suitable aerosol generating agent or aerosol generating agents may be included in the aerosol generating material of the present invention. Suitable aerosol generating agents include, without limitation: polyols such as sorbitol, glycerin, and glycols such as propylene glycol or triethylene glycol; substances that are not polyols such as monohydric alcohols, high boiling hydrocarbons, acids such as lactic acid, glycerol derivatives, esters such as diacetin, triacetin, triethylene glycol diacetate, triethyl citrate, or myristates, including ethyl myristate and isopropyl myristate, and aliphatic carboxylic acid esters such as methyl stearate, dimethyl dodecanedioate and dimethyl tetradecanedioate.

In some embodiments, the aerosol generating agent may be glycerol, propylene glycol, or a mixture of glycerol and propylene glycol. Glycerin may be present in an amount of from 10 to 20,956 by weight of the tobacco composition, for example, from 13 to 16,95 by weight of the composition or from 14 to 15,95 by weight of the composition. Propylene glycol, if present, may be present in an amount of from 0.1 to 0.3 95 by weight of the composition.

The aerosol generating agent may be included in any component of the tobacco composition, for example any tobacco component, and/or in the filler component, if present. Alternatively or additionally, the aerosol generating agent can be added to the tobacco composition separately. In both cases, the total amount of aerosol generating agent in the tobacco composition shall be as defined herein.

The tobacco compositions described herein contain nicotine. The nicotine content is from 0.5 to 1.5% by weight of the tobacco composition and can be, for example, from 0.8 to 1.2% by weight of the tobacco composition. In embodiments, the nicotine content can be from 0.8 to 1.0 95 by weight of the tobacco composition. It has unexpectedly been found that when used in a tobacco heating product, if the nicotine content is very high, it can lead to an unpleasant sensation during use during inhalation of the aerosol.

In compositions described in this document, where quantities are given in Uo by weight, for the avoidance of doubt, values are given on a dry weight basis, unless expressly stated otherwise. Thus, any water content that may be present in the tobacco composition or in any of its components is completely disregarded in determining the weight 956. The water content of the tobacco compositions described herein may vary and may be, e.g. , from 5 to 15 95 by weight. The water content of the tobacco compositions described herein may vary according to, for example, the temperature, pressure, and humidity conditions under which the compositions are stored. Water content can be determined by Karl Fischer analysis or by gas chromatography as described herein.

On the other hand, for the avoidance of doubt, even if the aerosol generating agent is a component that is in the liquid phase, such as glycerin or propylene glycol, any component other than water is included in the weight of the tobacco composition. However, if the aerosol-generating agent is provided in the tobacco component of the tobacco composition or in the filler component (if present) of the tobacco composition instead of or in addition to the agent added separately to the tobacco composition, then the aerosol-generating agent is not included in the weight of the tobacco component or filler component, but included in the weight of the "aerosol generating agent" in weight 95 as defined herein. All other ingredients present in the tobacco component are included in the weight of the tobacco component, even if they are not derived from tobacco (for example, non-tobacco fibers in the case of reconstituted tobacco obtained in a manner similar to paper).

In an embodiment, the tobacco composition comprises a tobacco component as defined herein and an aerosol generating agent as defined herein. In the variant

In an embodiment, the tobacco composition consists primarily of a tobacco component as defined herein and an aerosol generating agent as defined herein. In an embodiment, the tobacco composition consists of a tobacco component as defined herein and an aerosol generating agent as defined herein.

Reclaimed tobacco, obtained in a similar way to paper

The regenerated tobacco obtained in a similar manner to the paper is present in the tobacco component of the tobacco compositions described herein in an amount of from 70 to 100 95 by weight of the tobacco component. In embodiments, the recovered paper-like tobacco is present in an amount of 80 to 100 95 by weight or 90 to 100 95 by weight of the tobacco component. In an additional embodiment, the tobacco component consists mainly of or consists of regenerated tobacco obtained in a similar way to paper.

Recycled tobacco, obtained in a similar way to paper, means tobacco material formed by a process in which the tobacco raw material is extracted with a solvent to obtain an extract of solubles and a residue that contains the fibrous material, and then the extract (usually after concentration and optionally after additional processing) is recombined with the fibrous material from the residue (usually after cleaning the fibrous material and optionally with the addition of some non-tobacco fibers) by precipitation of the extract on the fibrous material. The method of re-combination resembles the method of obtaining paper.

BO The reconstituted paper-like tobacco can be any type of reconstituted paper-like tobacco known in the art. In a specific embodiment, reconstituted tobacco, obtained in a similar way to paper, is made from raw materials that include one or more of strip tobacco, tobacco stalks, and whole leaf tobacco. In an additional embodiment, the recovered tobacco, obtained in a similar way to paper, is made from raw materials consisting of strip tobacco and/or whole-leaf tobacco and tobacco stalks. However, in other embodiments, as an alternative or in addition to the composition of the raw materials, it is possible to use the formwork, small particles and particles remaining after airing.

The reconstituted paper-like tobacco intended for use in the 60 tobacco compositions described herein can be prepared by methods known to those skilled in the art for the preparation of reconstituted paper-like tobacco.

In some embodiments, reconstituted tobacco produced in a paper-like manner can be produced as follows.

According to Figure 1, tobacco fibrous materials, such as leaves, strips, stalks, formwork, fines and/or particles remaining after winnowing (in some embodiments leaves, strips and stalks), are first mixed with an aqueous solvent (e.g. water, water and water-miscible solvents such as ethanol).

Distilled water, deionized water or tap water can be used.

The tobacco suspension in the solvent is mixed, for example, by shaking or shaking, in order to increase the rate of extraction of the soluble part from the fibrous part of the tobacco. Mixing is usually carried out within a period of half an hour to no more than 6 hours. Mixing can be done in a stirrer, which contains a vessel and a paddle for mixing. The amount of solvent in the suspension can vary widely, from about 75 to 99% by weight of the suspension, depending on the tobacco fiber materials, the type of solvent and mixing equipment (in particular paddle type), and the temperature of the suspension. A typical suspension temperature range is from about 10°C to about 100°C.

The soluble part of the tobacco fibrous materials is separated from the insoluble fibrous part of the tobacco, for example, by pressing with a pneumatic, hydraulic or mechanical press or by filtration.

After separation, the fibrous part of the tobacco is usually subjected to mechanical cleaning to obtain a fibrous mass. Suitable mills can usually be disc mills or conical mills. The pulp will then be converted into a base web containing the tobacco pulp on a papermaking machine, such as a webbed paper machine. It is usually placed on a flat mesh conveyor where excess water is removed by gravity drainage and suction drainage.

At this stage, the non-tobacco fiber, such as cellulose, wheat fiber, or wood fiber, may include a fibrous portion derived from tobacco.

Z The soluble part of the tobacco raw material is concentrated using any known type of concentrator, such as a film evaporator or a vacuum evaporator. After concentration, ingredients such as aerosol generating agents (as defined herein), sauces such as cocoa, licorice, and acids such as malic acid, or flavorings (as defined herein) may be added and mixed with the concentrated tobacco solubles documents).

The concentrated tobacco solubles, potentially containing aerosol generating agents and/or sauces and/or flavorings, are then recombined with the dried tobacco fiber sheet to form reconstituted tobacco. Concentrated soluble substances can be added back to the fibrous web using various methods such as spraying, coating, impregnation, bonding.

Finally, the reconstituted tobacco is dried. It can be optionally cut into strips or rolled into a roll and then cut into coils or ground into cut tobacco.

In the context of this document, the terms "flavoring substance" and "flavoring agent" mean materials that, where permitted by local regulations, can be used to create a desired taste or aroma in a product for adult consumers. These may include extracts (for example, from licorice, hydrangea, Japanese white magnolia leaf, chamomile, gorse, cloves, menthol, Japanese mint, anise, cinnamon, greens, wintergreen, cherries, berries, peach, apples, drambuis, bourbon , scotch whiskey, whiskey, spearmint, peppermint, lavender, cardamom, celery, cascarilla, nutmeg, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, cassia, cumin , cognac, jasmine, ylang-ylang, sage, fennel, allspice, ginger, anise, coriander, coffee or mint oil of any species of the genus Mepipa), flavor enhancers, blockers of bitter receptors, activators or stimulants of sensory receptors , sugars and/or sugar substitutes (such as sucralose, acesulfame potassium, aspartame, saccharin, cyclamates, lactose, sucrose, glucose, fructose, sorbitol or mannitol) and other additives such as charcoal, chlorophyll, minerals, botanicals or agents for Fr refreshing the oral cavity. They can be artificial, synthetic or natural ingredients or mixtures thereof.

They can be presented in any suitable form, for example, in the form of oil, liquid or powder.

Examples of recovered paper-like tobacco that can be used in the present invention are presented below in Table 1.

If tape-cast tobacco is included, it may be present, for example, in an amount of from 10 to 30 95 by weight or from 10 to 20 95 by weight of the tobacco component.

Tape-cast tobacco that can be used in the tobacco compositions described herein can be prepared by methods known to those skilled in the art for producing tape-cast tobacco.

Rolled tobacco may contain tobacco or tobacco extract (or both), a filler, an aerosol generating agent (as defined herein), and a binder.

The filler referred to in this section as an ingredient in tape-moulded tobacco is different from the filler component that may be present in the tobacco compositions defined herein, but similar materials may be used for the filler component.

Roll-cast tobacco containing tobacco extract can be produced as follows.

Tobacco extract can be obtained using a method that involves processing

From tobacco using a solvent and may additionally include other processing steps (such as concentration). The extract may be formed by processing any suitable tobacco, such as single varieties or blends, cut tobacco or whole leaf tobacco, including Migdipia, and/or Vigieu, and/or Ogiepiai tobacco varieties.

In some embodiments, the tobacco extract can be obtained using a method that involves treating tobacco with water. In some embodiments, processing tobacco with water may include adding water to the tobacco, separating the resulting water-based liquid extract from the insoluble portion of the tobacco raw material, and optionally removing excess water to form the tobacco extract. Any suitable filtration method can be used, such as centrifugal solids filtration or fluidized bed vacuum filtration. Any suitable method of evaporative concentration can be used, such as rotating disk vacuum evaporation, falling or rising film vacuum evaporation. Techniques such as spray drying or freeze drying can also be used to reduce water content and removal. Such methods will be known to those skilled in the art of filtration and evaporative concentration. The pH of the tobacco extract can be adjusted to a value from 6 to 10.5.

In some embodiments, the tobacco extract can be obtained using a method that involves extraction using a supercritical fluid medium, for example, supercritical carbon dioxide. In some other embodiments, the tobacco extract can be obtained using a method that involves solvent extraction, which may involve a polyol or other suitable high-boiling liquids. In some cases, the extraction solvent may include glycerin and/or propylene glycol (and optionally water).

The filler may be required to give the tape-cast tobacco material a dry consistency, which means that the material can be processed at subsequent stages (shredding, mixing, twisting, bending, molding, etc.).

The filler may include one or more inorganic filler materials, including but not limited to chalk, perlite, vermiculite, diatomite, colloidal silica, magnesium oxide, magnesium sulfate, magnesium carbonate, and suitable inorganic sorbents such as molecular sieves. Chalk is particularly suitable. In some cases, the filler may include one or more organic filler materials, which include, but are not limited to, wood pulp, cellulose, and cellulose derivatives.

In some embodiments, the filler may act as a sorbent and/or base for other substances in the tape-cast tobacco. In some embodiments, it can act as a structure to absorb other substances before releasing them when heated. In some embodiments, it may function as a sorbent and/or base for an aerosol generating agent (as defined herein).

The binder may include one or more of alginate, cellulose or modified cellulose, starches or modified starches, gelatins, and natural or synthetic resins.

Suitable binders include, but are not limited to, alginate salts containing any suitable cation; celluloses or modified celluloses such as hydroxypropyl cellulose and carboxymethyl cellulose; starches or modified starches; polysaccharides such as pectin salts containing any suitable cation such as sodium, potassium, calcium or magnesium pectate; xanthan gum, guar gum and any other suitable natural gums; as well as their mixtures. In some embodiments, the binder contains, mainly consists of, or consists of one or more alginate salts selected from sodium alginate, calcium alginate, potassium alginate, or ammonium alginate.

Rolled tobacco may further include additional ingredients such as flavorings (as defined herein) and sauces (as defined herein).

Tobacco obtained by casting on a tape may additionally include heat-conducting particles. This can improve the intensity of the heat transfer applied to the tobacco obtained by casting on the tape.

In some embodiments, the ribbon-cast tobacco may further include additional tobacco material, in addition to the tobacco extract, such as ground tobacco, tobacco fiber, cut tobacco, pressed tobacco, tobacco stem, and/or reconstituted tobacco.

Tape-cast tobacco may be produced from a suspension, wherein the suspension contains the following components: an aerosol-generating material and water. In some embodiments, the suspension is extruded or cast and then dried to form an aerosol-generating material. In alternative embodiments, the suspension may be sprayed and then dried to form an aerosol generating material. In some embodiments, the method of producing an aerosol-generating material additionally includes an initial step of producing a suspension.

To form the suspension, the components of the cast tobacco can be added in any suitable order. In some embodiments, the slurry can be mixed during and/or after the addition of its components, and in these embodiments, it can be mixed for any suitable period of time. The period of time during which the suspension is subjected to mixing will depend on its composition and volume and may vary accordingly. In some embodiments, the slurry may be mixed, if necessary, to make the slurry composition substantially homogeneous and to ensure that the slurry has the necessary flow and viscosity characteristics for casting.

In some embodiments, the suspension preparation method may include the steps of (1) mixing an aerosol generating agent and a binder, (2) adding water and mixing, (3) adding a filler and mixing, (4) adding tobacco extract and mixing with the formation of a homogeneous suspension. Mixing after the addition of tobacco extract will usually be high shear mixing. In embodiments in which the binder is a solid, in step (1) a dispersion/suspension of the binder is created in an aerosol generating agent.

In some embodiments, the method of preparing the suspension may include the steps of (1) adding a binder to water and mixing, (2) adding an aerosol generating agent and mixing, (3) adding a filler and mixing, and (4) adding of tobacco granules, ground tobacco or tobacco extract and thorough mixing to form a homogeneous suspension.

The overhang can be cast as a sheet on a casting plate or as a strip in a strip casting machine. The suspension can then be dried using any suitable drying method. In some embodiments, the suspension may be dried at room temperature (ie, approximately 20-25 "C). In some embodiments, the suspension may be heated to effect drying. In some embodiments, the suspension may be dried in

From warm air (that is, in the oven). In some embodiments, the plate or tape on which the suspended moisture is held can be heated to effect drying. In embodiments where the suspension is heated, the suspension may be dried at any suitable temperature for any suitable length of time.

By any suitable method, the cast sheet can be removed from the casting plate or the strip from the strip casting machine. In some cases, the sheet and plate/strip are simply separated by applying force. In some cases, the sheet can be removed using a product to increase the space between the structure and the slab, such as a knife or blade ("squeegee knife"). Alternatively or additionally, the structure can be removed by increasing the temperature of the contact point between the structure and the slab. In some such embodiments 40, the structure can be removed from the plate using steam, which, in addition to increasing the temperature of the point of contact between the structure and the plate, causes water to be absorbed by the tape-cast tobacco, which facilitates its removal.

An example of tape-moulded tobacco containing tobacco extract is as follows. 45 Tobacco extract

Seven lots of Vigieu whole-leaf tobacco (4.5 kg per lot) were extracted with 80 kg of water (reverse osmosis-equivalent purity) at 60 °C for 25 minutes under gentle agitation. The resulting mixture was filtered and centrifuged and the resulting combined extracts (480 L) were concentrated using the evaporative concentration method to a solids content of 41.1 95 (in this context, "solids content" means the non-aqueous part of the aqueous extract). The extract was characterized by a nicotine content of 3.37 95 ( in terms of weight in a wet state) and a density of 1.21 g/cm3.

Tobacco obtained by molding on a tape

Water (756 g, purified by reverse osmosis) was placed in a high shear mixer. During mixing, powdered sodium alginate (15.01 g) was slowly added to ensure uniform mixing and complete hydration to a homogeneous viscous fluid medium. Glycerol (24.99 g) was added to the high shear mixer with continuous mixing. Then, during continuous mixing, chalk (156.99 g) was added in the form of a slow powder flow under high shear force. Finally, tobacco extract (61.26 g, prepared as above) was added under continuous high shear mixing until a homogeneous free-flowing suspension was formed.

After the formation of a homogeneous free-flowing suspension, the material was ready for casting in the form of a sheet.

The overhang was then cast onto a stainless steel casting plate to a thickness of 2 mm using a casting knife. This ensured a constant thickness of the suspension, which was then dried. Drying can be done by air drying under ambient conditions for about 24 hours or in an oven at a temperature of about 45-557C for 0.5-5 hours (minimum time used to reduce loss of volatiles). The dried sheet was then removed from the plate and conditioned by holding at 22°C and 60 95 relative humidity (RH) for 48 hours. In some cases, the dried sheet was cut from the casting plate with a "squeegee" knife.

The tobacco material obtained as a result of molding was characterized by a nicotine content of 6.7 mg/g (MLLIV), 7.15 mg/g (MV), a glycerol content of 90.3 mg/g (M/L/B), 96.4 mg/ g (OMMV) and with a water content of 6.3 vol.

Roll-cast tobacco typically contains tobacco powder, a binder such as modified celluloses such as hydroxypropyl cellulose and carboxymethyl cellulose (CMS), an organic filler such as wood pulp, and an inorganic filler such as chalk . Tobacco, which contains tobacco obtained by molding on a tape, can be obtained as follows.

The organic filler, such as wood fiber, is pretreated to obtain desired characteristics such as fiber length, twist, twist angle, etc.

Tobacco (leaf plates and stem) is ground into a powder with a particle size of "200 microns, for example, "100 microns. It is added to a hydrated binder, an organic filler such as wood fiber, and glycerin. An inorganic filler, such as chalk, is optional.

The resulting suspension is then cast, for example, on an endless steel casting belt, and dried in the form of sheet material, which can be further shredded or rolled into a roll.

Table C

Materials similar to the materials described above in this section, but without the inclusion of tobacco extract or tobacco powder, can be used in the composition of the filler component of the tobacco composition.

Determination of water content

In compositions described herein, 96 by weight refers to dry weight values, unless expressly stated otherwise. Thus, any water content that may be present in the tobacco composition or any of its components is completely disregarded in determining the weight 95. However, other liquid components, such as the aerosol generating agent, are included in the weight 95. The water content of the tobacco compositions described herein may vary and may range, for example, from 5 to 15 95 by weight. Water content can be determined by Karl Fischer analysis or by gas chromatography (55).

Determination of water content using Karl Fischer analysis

Determination of water content using Karl Fischer analysis was carried out on a Karl Fischer volumetric titrator M30 from Mesh Sheg ToiIedo. Before testing the samples, the background water content in the extraction solvent (methanol) was determined and the value recorded in the analysis method.

About 0.5 g of the material to be analyzed was carefully weighed (4 decimal places) in a 100 ml conical flask and the weight was recorded. 50 mL of dry methanol was measured into a conical flask, which was then sealed and allowed to stir on a plate shaker (155 rpm) for 30 minutes. About 2 ml of the sample extract was transferred to a syringe and introduced into the titration device (the weight was determined by back-weighing the syringe). The results were recorded in the form of Us by weight of the water content in the sample. Samples were calculated in triplicate and the average values were recorded along with the standard deviation.

Determination of water content using gas chromatography

Method C - a brief description. 2.0000 g and 0.1 g of the sample are weighed in a conical flask with a volume of 150 ml.

50 ml of extraction solution (methanol suitable for use in NRIS with 1.5 mg/ml of n-heptadecane and 1.5 mg/ml of IRA internal standards) is added to it.

The flask is then closed with a lid and placed on a shaker (orbital or reciprocating) for 4 hours at 160 rpm.

The flask is then removed from the shaker and allowed to stand for 1 hour, after which an aliquot of the extract is transferred to a vial for OS.

The extract in the OS vial is analyzed using a two-column C (see Table 4 below for parameters) against the working calibration solutions that were previously prepared (see Table 5 below). thermal conductivity of the detector with glass wool filling with glass wool (Ratio of flow separation.

Device for generating inhalable aerosol

The tobacco compositions described herein can be used in a device for generating an inhalable aerosol. The device contains the tobacco composition described in this document and a heating agent that provides evaporation of the components used to form the aerosol. A number of such devices are known in the art, and an example is disclosed in PCT/EP2014/072828, which is thus expressly incorporated herein by reference in its entirety.

In some embodiments, the heating means is an electric heating means. In some embodiments, the electric heating means is an electrically resistive heating element. In some embodiments, the heating of the aerosol generating material does not cause any significant burning of the material. In some embodiments, the heating does not cause combustion or substantial combustion of the aerosol generating material. In some embodiments, the device is a device that heats but does not burn, also known as a tobacco heating device or a tobacco heating product. Such devices are non-burning smoking products designed as an alternative to traditional cigarettes that are capable of burning. These devices provide vaporization of tobacco components by heating the tobacco material; while avoiding pyrolysis or burning of tobacco or volatile substances. Vaporized components condense to form an inhalable aerosol. An aerosol often contains water, an aerosol generating agent (as defined herein), nicotine, and optionally other tobacco components such as flavorings and flavoring agents. Thus, in some embodiments, the device is a device in which the tobacco is heated to vaporize the components without pyrolysis or combustion of the tobacco.

The use of electricity to heat the tobacco composition in a smoking product has many advantages. In particular, it has many advantages over the use of combustion. Burning represents

It is a complex process by which aerosols are formed due to a combination of interrelated physicochemical processes, which may include oxidative decomposition, pyrolysis, pyrosynthesis and distillation. In most cases, it leads to the formation of complex aerosols. For example, the smoke generated in a combustible smoking product containing tobacco is a complex dynamic mixture of more than 5,000 identified constituents. Exothermic combustion processes can sustain themselves and can provide values of the intensity of heat generation and the amount of thermal energy sufficient to decompose the combustible matrix. In some cases, the matrix may be completely decomposed to an ash residue, which may contain inorganic, non-combustible materials. Because of the exothermic combustion reaction, very high temperatures can be reached during the burning of cigarettes. In the period between puffs of a cigarette (the smoldering period between puffs), the center of the combustion zone in the tobacco rod of a cigarette can reach temperature values of up to 800 "С. During the performance of a puff of a cigarette, the peripheral section of the combustion zone in the tobacco rod of a cigarette can reach temperature values of up to 910 "С.

The use of electric resistance heating systems (such as some heat-but-not-burn devices, also known as tobacco heaters or tobacco heating devices) is advantageous because the intensity of heat generation is easier to control and it is easier to produce a lower level of heat compared to using combustion to generate heat. In some embodiments, the device includes a switch that allows the user to initiate electrical heating.

The use of electrically heated systems thus provides greater control over the formation of an aerosol from the tobacco composition. In addition, it allows the formation of an aerosol without combustion, rather than decomposition due to combustion.

In some embodiments, the devices of the present invention are capable of providing multiple portions or doses of an aerosol. This means that the tobacco composition can be heated to produce enough aerosol to provide several puffs. This can be achieved by heating the tobacco composition for a period of time sufficient to produce a volume of aerosol suitable for multiple servings. In some embodiments, this may include continuous heating of the tobacco composition. Alternatively, it may involve successive, shorter periods of heating the tobacco composition, with each period not necessarily providing one portion or dose of aerosol.

In some embodiments, the device can be designed with the ability to heat the tobacco composition to a temperature in the range of approximately 50-350 "C, 100-350 "C, 150-350 "C, 150-330 "C or 180-300 "C.

In some embodiments, the tobacco composition or the smoking material that contains the tobacco composition may be provided in a cartridge, and the cartridge may be inserted into the device. In some of these embodiments, this cartridge may be replaceable. In some embodiments, the cartridge may be combined with other parts of the aerosol generating device in any suitable manner. In some embodiments, it may be attached to other parts of the device using a friction fit, and/or a screw fit, and/or a press fit. Thus, the tobacco composition can be provided in a smoking product, which is a consumable item and is intended for use in conjunction with a device for heating the smoking material.

Smoking product

In the context of this document, the term "smoking material" includes materials that, when heated, provide volatile components, usually in the form of an aerosol. "Smoking material" includes any material containing tobacco and may, for example, include one or more of tobacco, tobacco derivatives, expanded tobacco, cut tobacco, reconstituted tobacco, or tobacco substitutes, without limitation to the tobacco compositions described herein. . "Smoking material" may also include other non-tobacco products which, depending on the product, may or may not contain nicotine.

A known device that heats a smoking material to vaporize at least one component of the smoking material, typically to form an inhalable aerosol, without burning or combusting the smoking material. Such a device is sometimes referred to as a "heat-but-not-burn" device, or a "tobacco heater," or a "tobacco heater," etc. The device is usually elongated in most cases, with an open end, sometimes referred to as the mouth end. The smoking material may be in the form of or provided as part of a cartridge, or cassette, or rod that can be inserted into the device. A filtering system may be provided at the mouth end to filter and/or cool the vaporized material as the material is inhaled by the user. As a "permanent" part of the device, a heater for heating and vaporizing the smoking material may be provided, or it may be provided as part of the smoking product or consumable element, which is removed and replaced after use. "Smoking product" in this context is a device, or product, or other component containing a smoking material, which during use is heated to vaporize the smoking material, and optionally other components. During use, in particular in the main application options presented, the smoking material does not burn or burn. The tobacco compositions described herein are particularly useful in such smoking products, and the smoking material may contain tobacco compositions.

Next, according to figure 4, an example of a consumable element 100 for use with a device for heating smoking material is schematically shown. Consumable element 100 has a mouthpiece 101 and a cylindrical rod of smoking material 102.

The mouthpiece 101 can be formed, for example, from paper, such as in the form of a spirally wound paper tube, cellulose acetate, cardboard, corrugated paper such as corrugated heat-resistant paper or corrugated parchment paper, and polymeric materials such as low-density polyethylene (LDPE ), or some other suitable 60 material. Mouthpiece 101 may include a tube. The tube can be a hollow tube. Such a hollow tube can provide a filtering function by filtering vaporized smoking material. As shown, the mouthpiece 101 may be elongated in order to separate it from the very hot part(s) of the main device that heats the smoking material.

In an embodiment not shown, the mouthpiece may contain a filter element.

The filter element can be a filter rod and can be made, for example, of cellulose acetate. The filter element, if present, may be located at the lower end of the mouthpiece.

Further, according to figure 5, the mouthpiece 201 assembly may contain an element 204 for cooling.

Element 204 may be a monolithic rod that has first and second ends and that includes multiple through holes passing between the first and second ends. As shown in Figure 5, a second hollow tube 206 may be located on the other side of the cooling element 204, which separates the cooling element 204 from the very hot part(s) of the main device that heats the smoking material, and thus protects the cooling element 204 from the effects of high temperatures and also helps improve aerosol formation as it can help prevent condensation. The second tube 206, again, can be formed, for example, from paper, for example in the form of a spiral wound paper tube, cellulose acetate, cardboard, corrugated paper such as corrugated heat-resistant paper or corrugated parchment paper, and polymeric materials such as such as low density polyethylene (LDPE) or some other suitable material. The tube 205, which is the end that is brought to the mouth, and the second tube 206 provide a support for the element 204 for cooling. The tube 205, which is the end that is brought to the mouth, may have a filtering function and may sometimes be referred to as a tube filter.

The cooling element 204 in this example is located in most cases in the center of the mouthpiece assembly 201, but in other examples it may be located slightly closer to one end or the other end of the mouthpiece assembly 201. In the example of Figure 5, mouthpiece tube 205, cooling element 204, and second tube 206 are held together by rim paper 203 tightly wound around mouthpiece tube 205 , element 204 for cooling and a second tube 206 to connect them together. In this sense, the assembled mouthpiece 201 is "pre-assembled".

In one particular example, the first tube 205, which is the mouth end, may be 11 mm long, the cooling element 204 may be 19 mm long, and the second tube 206 may be 11 mm long, and the outer diameter of the mouthpiece 201 in the collection as a whole can be 5.4 mm. Excluding the rim paper 203, the outer diameter of the cooling element 204, the mouth end tube 205, and the second tube 206 may be, for example, in the range of 5.13 mm to 5.25 mm, while 5 .25 mm is one preferred option. Other sizes may be used depending on, for example, the particular application, the typical temperature of the aerosol or vapor being supplied, the nature (material) of the aerosol or vapor and the smoking material, etc.

As also shown in Figure 5, the mouthpiece assembly 201 may then be attached to the smoking material 202 with an additional rim paper 207 that is wound around the mouthpiece assembly 201 and at least the adjacent end of the smoking material 202. In other examples, the mouthpiece assembly 201 is not pre-assembled, and instead the consumable element 200 is formed by wrapping the rim paper 207 around the cooling element 204, the mouthpiece tube 205, the second tube 206, and the smoking material 202 in virtually one pass without providing a separate rim paper for mouthpiece parts components.

As shown in Figure 5, the mouthpiece assembly 201 may include a cooling element.

The cooling element has through-holes that can run substantially parallel to the central longitudinal axis of the rod.

Through holes can be located in most cases in the radial direction of the element, if viewed in a side cross-section. That is, in the example, the element has internal walls that define through holes and that have two main configurations, namely radial walls and central walls. The radial walls run along the radii of the cross-section of the element, and the central walls are located in the center of the cross-section of the element.

The central walls in one example are annular, although other regular or irregular cross-sectional shapes may be used. Similarly, the cross-section of the element in one example is annular, although other regular or irregular cross-sectional shapes may be used.

In an embodiment, most of the through holes have a hexagonal or generally hexagonal cross-sectional shape. In this embodiment, the element has a structure that can be called a "honeycomb" structure when viewed from one end.

The element can be practically incompressible. It can be formed from a ceramic material or from a polymer, for example, a thermoplastic polymer, which can be an extrudable plastic material.

In an embodiment, the porosity of the element is in the range from 6bO 95 to 7595.

Porosity in this sense can be a measure of the percentage of the lateral cross-sectional area of the element occupied by through holes. In an embodiment, the porosity of the element is between about 69 95 and 70 95.

Other variants of the element for cooling the aerosol are disclosed in

PCT/582015/051253, which is hereby incorporated herein by reference in its entirety in its entirety, and in particular by reference to Figures 1-8 and the description from page 8, line 11 to page 18, line 16.

In additional embodiments, the aerosol cooling element may be formed from a sheet of material that is folded, corrugated, or bent to form through holes. The sheet material may be made of, for example, a metal such as aluminum; polymeric plastic materials such as polyethylene, polypropylene, polyethylene terephthalate or polyvinyl chloride; or paper.
